Patients will undergo a total of three separate CEUS exams. These exams will consist of the baseline study the morning prior to TACE therapy, a study 1-2 weeks post treatment that will coincide with clinical post-procedure follow-up by the interventional radiologist, and a study approximately one month post treatment when patients return for clinically scheduled CE-CT/MRI follow-up. If the patient fails to show up for the 1-2 week CEUS exam, they will not be excluded from the final ultrasound exam. Procedures and equipment for this trial will be used in accordance with standard clinical protocols and good clinical practices already in place at our hospitals.
